Xiaomi's Hyper OS 4 may bring Privacy Display to more phones, but how does it compare to Samsung's S26 Ultra?

At a glance:

• Xiaomi is reportedly developing a Privacy Display feature for Hyper OS 4, potentially arriving later this year.
• The feature may use a software-based approach, differing from Samsung's hardware-driven Flex Magic Pixel technology in the Galaxy S26 Ultra.
• A software solution could enable the feature on older devices, avoiding hardware limitations seen in Samsung's implementation.

Samsung's Privacy Display: Hardware innovation with trade-offs

The Samsung Galaxy S26 Ultra introduced a Privacy Display feature earlier this year, leveraging Flex Magic Pixel technology to physically adjust pixel orientation and narrow viewing angles. This hardware-based approach allows users to restrict screen visibility to specific areas or the entire display, making it harder for shoulder surfers to glimpse sensitive information. However, the technology has faced criticism for reducing screen brightness and causing eye strain compared to the S25 Ultra, as noted by reviewers like Zac Kew-Dennis.

Xiaomi's software-driven alternative: A different path

Tipster Yogesh Brar suggests Xiaomi is working on a similar feature through its Hyper OS 4 update, likely using a software-based method. Unlike Samsung's hardware solution, this could involve overlaying a draggable privacy shade—reminiscent of BlackBerry's Privacy Shade on Android devices—which blackouts most of the screen except for a selected area. While less technically ambitious, a software approach might avoid brightness compromises and offer broader compatibility across Xiaomi's device lineup.

Technical and practical implications

Samsung's hardware-driven Privacy Display requires specialized screen components, limiting its availability to newer models. In contrast, Xiaomi's software-based strategy could theoretically extend the feature to older phones via OS updates, eliminating the need for specific hardware or screen protectors. However, software solutions may lack the precision of physical pixel manipulation, potentially offering a less seamless user experience.

Market competition and user impact

The rivalry between Samsung and Xiaomi highlights a broader trend in mobile security features. Samsung's approach prioritizes hardware integration but faces usability challenges, while Xiaomi's potential software-first strategy could democratize privacy tools. Users may benefit from increased choice, though the effectiveness of each method remains to be seen. Analysts will likely watch how Xiaomi balances functionality with performance in its implementation.

Looking ahead: What to expect

Xiaomi's Hyper OS 4 update is expected later this year, though specifics about the Privacy Display feature remain unclear. If successful, it could pressure Samsung to refine its hardware approach or adopt software enhancements. For now, both companies are betting on privacy-conscious features to differentiate their flagship devices in a competitive Android market.

Conclusion: Innovation through divergence

While Samsung's Privacy Display represents a bold hardware leap, Xiaomi's software-centric path offers a pragmatic alternative. The outcome will depend on user adoption, technical execution, and whether Xiaomi can avoid the pitfalls that have plagued Samsung's implementation. Either way, the race to secure mobile screens underscores the growing importance of privacy in smartphone design.
